To all whom it may concern: 7

Be it known that I, CARLE'I'ON RUHE, a citizen of the United States, residing at Olean, in the county of Cattaraugus and State of New York, have invented certain new and useful-Improvements in Combined Fleshing and Unhairin Machines,of which the following is a speci cation. 1

My invention relates to a combined fleshing and dehairin machine.

An important 0 j ectfof the invention is to provide a machine. which will effectively remove the flesh and] hair from the opposite sides of hide in ahighly expeditious and convenient manner. 4

A further object ofthe invention is to provide means'for-facilitating the insertionof the hide or stock within the machine.

Other objects and advantages of the in vention will be apparent during the course of the following description.

In the accompanying drawings forminga part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a front side elevation of-a 'ma-- chine embodying the invention,

Fig. 2 is an end elevation of the same,

Fig.3 is a transverse sectional view taken on line 33 of Fig. 1, with partsin eleva tion, j g l Fig. 4 is a detail section taken'on line H of Fig. 3, and, I

Fig. 5 is a detail view of an adjustable bearing. p

In the drawings, wherein for the pur pose of illustration is shown a preferred embodiment'of my invention, the numeral I 10 designates the frame-work of the 1113.1 chine, as a whole, comprising a base 11, which is preferably rectangular. Formed upon this base are rear stationary end m'em bers or standards 12, as ShOWIL' The nu meral 13, designates coacting sliding end members or standards, which are connected by a section of material 1 1 whereby they As more clearly shown in Fig. 1, the standards 13 are provided at their ends with inward projectionsor flanges 15, overhanging tracks 16 formed upon the base 11. These flanges'and tracks are provided with grooves for receiving bearing balls 17. Means to be described are provided to reciprocate the standards 13 toward, and away from the standards 12.

Thenumeral 18 designates the fieshing COMBINED ma mas AND; UNiiAInING MACHINE.

cylinder or roll, provided upon its periphery with spiral blades 19, adapted to contact with the flesh side of thehide or stock to remove the flesh therefrom. The roll 18 is rigidly mounted upona shaft 20, journaled through adjustable bearings 21 slidably mounted in slots 22 "in the standards 12.

Adjusting bolts 23 are screw-threaded through outwardly projecting cars 24" and adapted to engage the adjustable bearings Specification of Letters Patent. I Patented Apr. 24 1917. Application fiIedMay 9, 1916. I Serial No. 96,374. I

roll 21.- Co-acting with the fleshing roll 18 v is a supporting roll 21, preferably formed of hard rubber. This roll is arranged oppositethe fleshing roll 18 and the hide or stock is adapted to pass between these rolls. The'roll 21 is rigidly mounted upon a shaft 22, j ournaled within suitable bearings formed in the reciprocatory end members or standards 13, as shown.

The numeral 23 designates an unhairing roll or cylinder, provided upon its periphery with blades 24 adapted to contact with the hair side of the'hide andremove the hair therefrom. The unhairing roll 23 is rigidly mounted upon'a shaft 25, j ournaled through adjustable bearings formed in the end members or standards 13. These adjustable bearings are identical with the bearings described in connection with the fleshing roll and the one description will suffice for both. I

Arranged opposite the unhairing roll 23 is a supporting roll 26, rigidly mounted upon the shaft 27 which is journaled T through bearings formed in the standards 12.

ings formed in the reciprocatory shafts 13.

At this point it might be well to state that when the standards 13 are moved forwardly the'feeding roll 23 is moved away fromor out of contact with the coacting rolls 28 and 29; supporting roll 21 is moved away from the fieshing roll 18; and the unhairing roll 23 is moved away from the sup porting roll 20. By this means a suitable space or passage is provided, within which the operator suspends the hide, such hide being thrown over the top 34 and about the feeding roll 32. The feeding roll will slip when contacting with the hide, prior to this feeding roll being brought into close proximity of the coacting feeding rolls 28 and 29.

As clearly shown in Fig. 1, the shaft 20 constitutes the power shaft and is equipped with a pulley 35, for receiving rotation from a suitable source of power. The shaft 20 is provided with a sprocket wheel 36 engaging a sprocket chain 37, extending upwardly to engage a sprocket wheel 38 rigidly mounted upon the shaft 31. Upon its opposite end the shaft 31 is provided with a gear or pinion 39, adapted to engage a gear 40 rigidly mounted upon the shaft 33. The gear 40 is adapted to engage with a gear 41, rigidly mounted upon the shaft 30. When the side members or standards 13 are moved to the inner position, it is obvious that the rotation of the shaft 31 will be imparted to the shafts 33 and 30, as indicated by the arrows. It is to be understood that instead of employing gears, I may substitute friction pulleys. The shaft 20 carries a second sprocket wheel 42 engaging adepending sprocket chain 43, which engages a sprocket wheel 44, rigidly mounted upon the shaft 27.

The numeral 45 designates an arm, having an opening 46 formed in its upper end to pivotally receive the end of the shaft 20. The lower end of the arm 45 is pivotally connected with an angularly arranged arm 47 by means of a stub shaft 48. The upper end of the arm 47 is pivotally mounted upon the end of the shaft 25. Rigidly mounted upon one end of the shaft 20 is.a sprocket wheel 49, engaged by a sprocket chain 50 engaging a sprocket wheel 51. The sprocket wheel 51 is rigidly mounted upon stub shaft 48 which is free to rotate. The stub shaft 48 has a sprocket wheel 52 rigidly mounted thereon which is engaged by a sprocket chain The sprocket chain 53 extends upwardly and engages a sprocket wheel 54, rigidly mounted upon a stub shaft 55, which is pivotally mounted upon the arm 47 The stub shaft 55 has a gear 56 rigidly mounted thereon, engaging the gear 57, which is rigidly mounted upon the shaft 25. It is thus apparent that the rotation of the shaft 20 is transmitted to the shaft 25, and the arms 45 and 47, together with the gearing form a flexible connection whereby the shaft 25 may be driven irrespective of the sliding movement of the end members 13. Rigidly mounted upon one end of the shaft 27 is a sprocket wheel 58, engaged by a depending sprocket chain 59, engaging a sprocket wheel 60, which is rigidly mounted upon a shaft 61. The shaft 61 is ournaled through bearings 62.

Arranged above the shaft 61 is a counter shaft 63, journaled through suitable bearings in the base 11. This shaft is provided with gears or pinions 64 rigidly secured thereto, and engaging racks 65, formed integral with the standards 13. It is thus apparent that the rotation of the counter shaft 63 will serve to reciprocate the standards 13. Rigidly mounted upon the shaft 63 is a sprocket Wheel 66, engaged by a sprocket chain 67. This sprocket chain engages a sprocket wheel 68 rotatably mounted upon the shaft 61. Rigidly mounted upon shaft 63 is a second sprocket wheel 69 engaged by a crossed sprocket chain 70, engaging a sprocket wheel 71, rotatably mounted upon the shaft 61. The sprocket wheels 61 and 71 are provided respectively with clutch elements 72 and 73 adapted for engagement with a clutch member 74 which is splined upon the shaft 61.

The clutch element 74 is provided upon its periphery with a groove 75, receiving the upper forked end 76 of a lever 77 This lever 77 is pivoted to a longitudinal bar 7 8, and is adapted to swing in a vertical plane longitudinally of the shaft 61. The lever 77 carries arms 79, rigidly connected therewith. It is thus apparent that by swinging the arms 79 the lever 77 may be shifted and the clutohmember 74 brought into engagement with either of the clutch elements 72 and 73. The means to move the arms 79 comprise pedal levers 80, having their inner ends pivotally connected with the arms 79 and their outer ends arranged upon and contacting with a supporting bar 81.

Automatic means are provided to lock the side members or standards 13 in the outer or inner positions and to return the clutch member 74 to the normal inactive position. Such means comprises vertically swinging levers 82 and 83, pivoted upon supports 84. The inner ends of the levers 82 and 83 are preferably longitudinally slotted to receive a pivot element or shaft 85, carried by a depending link 86. The link 86 has pivotal connection at its lower end, as shown at 87, with a vertical swinging lever 88. The forward end of this lever is pivotally mounted upon a stationary rod 89, attached to the base 11. The opposite end of the lever 88 is forked, as shown at 90, and this forked end straddles the lever 77. The lever 77 and the lever 88 are adapted to move at a right angle to each other. When the lever 77 is swung in either direction to assume an angular position whereby the clutch member 74 engages either of the coacting clutch members, such lever 77 will contact with one side of the forked end 90. When the lever 88 is now moved upwardly such forked end notch 98. It is thus apparent that when the standards 13 have moved inwardly or outwardly to the end of their travel,the corresponding bolt will first be depressed and subsequently move upwardly to enter its notch in the standard whereby the standard is locked against movement. Upon the depression of the bolt the outer end of the lever 83 is swung upwardly causing the upward movement of the link 86, and the corresponding movement of the lever 88. This movement of the lever 88 shifts the lever 77 to theneutral position and thus stops the rotation of the shaft 63.

The operation of the machine is as follows: i

When the operator desires to feed the hide into the machine, he depresses the left pedal lever 80 and brings clutch member 7 4- into engagement with clutch element 72. The rotation of the shaft 61 is therefore transmitted to the shaft 63, and this shaft 63 through the medium of the gears 64;, shifts the standards 13 to the left, forming the space or passage between the coacting rolls, as above explained. The operator then throws the hide over the top 3tand around or about the feeding roll 32. The operator then depresses the pedallever 80 to the right and the clutch mechanism is rendered active to drive the shaft 63 in anopposite direction whereby the standards 13 travel inwardly. The standards 13 are locked in the extreme inner or outer. position as before described. When the standards 13 are in the inner position, the feeding rolls 28 and 29 and 32 have proper clamping engagement with the hide and tend to feed it upwardly at a proper speed. The rolls 18, 21 and 23, 26 have their portions contacting with the hide turning downwardly, in an. opposite direction to the upward travel of the hide which is effected by the feeding rolls. In this manner the flesh and hair are removed from the opposite sides of the hide in a highly efficient manner. The upper end ofthe hide which is first clamped between the inner rolls, and which is not acted upon by the unhairing and fleshing rolls, may be subjected to such action by inverting the hide and again passing the same through the machine.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, slze, and arrangement of parts may be re sorted to without departing from the spirit of the invention or the scope of the subjoined claims.- 3
